(Alif Lam Ra. (This is) a Book, the verses whereof are perfect (in every sphere of knowledge, etc.), and then explained in detail from One (Allah), Who is Wise and well-acquainted (with all things)) (11:1)

So the expressions in the Qur'an are perfect and its meanings are explained. Further, every word and meaning in the Qur'an is eloquent and cannot be surpassed. The Qur'an also mentioned the stories of the people of the past; and these accounts and stories occurred exactly as the Qur'an stated. Also, the Qur'an commanded every type of righteousness and forbade every type of evil, just as Allah stated,

[وَتَمَّتْ كَلِمَةُ رَبِّكَ صِدْقاً وَعَدْلاً]

(And the Word of your Lord has been fulfilled in truth and in justice) (6:115). meaning, true in the stories it narrates and just in its Laws. The Qur'an is true, just and full of guidance. It does not contain exaggerations, lies or falsehood, unlike Arabic and other types of poems that contained lies. These poems, conform with the popular statement, "The most eloquent speech is the one that contains the most lies!'' Sometimes, one would find a long poem that mainly contains descriptions of women, horses or alcohol. Or, the poem might contain praise or the description of a certain person, horse, camel, war, incident, fear, lion, or other types of items and objects. Such praise or descriptions do not bring any benefit, except shed light on the poet's ability to clearly and eloquently describe such items. Yet, one will only be able to find one or two sentences in many long poems that elaborate on the main theme of the poem, while the rest of the poem contains insignificant descriptions and repetitions.

As for the Qur'an, it is entirely eloquent in the most perfect manner, as those who have knowledge in such matters and understand Arabic methods of speech and expressions concur. When one reads through the stories in the Qur'an, he will find them fruitful, whether they were in extended or short forms, repeated or not. The more these stories are repeated, the more fruitful and beautiful they become. The Qur'an does not become old when one repeats reciting it, nor do the scholars ever get bored with it. When the Qur'an mentions the subject of warning and promises, it presents truths that would make solid, firm mountains shake, so what about the comprehending, understanding hearts When the Qur'an promises, it opens the hearts and the ears, making them eager to attain the abode of peace - Paradise - and to be the neighbors of the Throne of the Most Beneficent. For instance, on the subject of promises and encouragement, the Qur'an said,

(Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, and then it should quake Or do you feel secure that He, Who is over the heaven (Allah), will not send against you a violent whirlwind Then you shall know how (terrible) has been My warning) (67:16-17).

On the subject of threats, the Qur'an said,

[فَكُلاًّ أَخَذْنَا بِذَنبِهِ]

(So We punished each (of them) for his sins) (29:40). Also, on the subject of soft advice, the Qur'an said,

(Tell Me, (even) if We do let them enjoy for years. And afterwards comes to them that (punishment) which they had been promised. All that with which they used to enjoy shall not avail them) (26:205-207).

There are many other examples of the eloquence, beauty, and benefits of the Qur'an.

When the Qur'an is discussing Laws, commandments and prohibitions, it commands every type of righteous, good, pleasing and beneficial act. It also forbids every type of evil, disliked and amoral act. Ibn Mas`ud and other scholars of the Salaf said, "When you hear what Allah said in the Qur'an, such as,

[يَـأَيُّهَا الَّذِينَ ءَامَنُواْ]

(O you who believe!), then listen with full attention, for it either contains a type of righteousness that Allah is enjoining, or an evil that He is forbidding.'' For instance, Allah said,

(He (Muhammad ) commands them for Al-Ma`ruf (i.e. Islamic Monotheism and all that Islam has ordained); and forbids them from Al-Munkar (i.e. disbelief, polytheism of all kinds, and all that Islam has forbidden); he allows them as lawful At-Tayyibat(i.e. all good and lawful things), and prohibits them as unlawful Al-Khaba'ith (i.e. all evil and unlawful things), he releases them from their heavy burdens and from the fetters (bindings) that were upon them) (7:157).

When the Ayat mention Resurrection and the horrors that will occur on that Day, and Paradise and the Fire and the joys and safe refuge that Allah prepared for His loyal friends, or torment and Hell for His enemies, these Ayat contain glad tidings or warnings. The Ayat then call to perform good deeds and avoid evil deeds, making the life of this world less favorable and the Hereafter more favorable. They also establish the correct methods and guide to Allah's straight path and just legislation, all the while ridding the hearts of the evil of the cursed devil.
